In this study, a field experiment was conducted at the Minqin Experimental Station of the Gansu Institute of Hydraulic Sciences between 2016 and 2018 to investigate the influence of dual mulching with crushed wheat straw padding and plastic film combined with different irrigation amounts on soil nutrients and the growth of edible sunflower. The experiment was conducted using a two-factor design with four mulching methods and three irrigation levels. The results of the study revealed that the soil nutrients under the dual mulching of crushed wheat straw padding and plastic film showed significant improvement. The soil nutrient status showed a significant improvement by mulching in comparison with no mulching, and the dual mulching of crushed wheat straw padding and plastic film gave the best results compared to other mulching methods. The medium irrigation level shows better soil nutrient improvement as compared to other irrigation levels. The results obtained from the current experimental study in the Minqin oasis area with drought and little rain revealed that edible sunflowers can be grown under the dual mulching method of crushed wheat straw padding and plastic film as an optimal conservation tillage method.
The current study examines the contamination of microplastics in three greenhouse types: abandoned, normal, and simple. The findings revealed that the abundance of microplastics was found to be the highest in the abandoned greenhouse, followed by the normal greenhouse and simple greenhouse. The mean abundance of microplastic organic fertilizer and irrigation water was also high.[…]
The study examines the distribution of residual film after eight years of film mulching in mid-April 2018. Results from the study revealed that eight years of mulching significantly increased the quantity of agricultural mulch film residues in the soil. The size of residual film fragments was found to vary from 0.25 cm2 to 109 cm2,[…]
A study in Yuanmou County, Yunnan Province, investigated microplastic pollution in different land uses, including facility farmland, traditional farmland, orchard, grassland, and woodland. Results showed a significant difference in microplastic abundance and characteristics between different land use types. Facility farmlands, traditional farmlands, and orchard lands had higher microplastic abundance than grasslands and woodlands. The main[…]
The study analysed 225 soil samples from maize planting zones in northern China, revealing that long-term plastic film mulching increases microplastic pollution in agricultural soils. The abundance of microplastics was significantly higher in mulched soils (754 ± 477 items kg-1) than in non-mulched soils (376 ± 149 items kg-1). The length of time with film[…]
The study examined the relative abundances and morphological distributions of microplastics (MPs) in water, sediments, and farmland soils in the Caohai Lake region. The estuary in the study area was considered a potential sink for MP transportation. Transparent and black MPs accounted for a large proportion of MPs in the five environments, with possible sources[…]
